WASHINGTON-The White House on Friday said it remains in close touch with both Pakistan and India and urged them to avoid taking any steps that may further increase tensions between them following last month's attacks in Mumbai. The US reacted after India warned its citizens that it was unsafe to travel to Pakistan and Islamabad cancelled Army troops leave and moved some of its troops from its Western border. US National Security Council spokesman Gordon Johndroe said the White House had seen reports about both sides actions and was staying in touch with its Embassies in the region. 'We hope that both sides will avoid taking steps that will unnecessarily raise tensions during these already tense times', Johndroe said. 'We continue to be in close contact with both countries to urge closer cooperation in investigating the Mumbai attacks and in fighting terrorism generally'. Meanwhile, Pakistan's Ambassador to the US, Husain Haqqani, said Pakistan does not seek war but 'we need to be vigilant against threats emanating from the other side of our Eastern border'. With tensions on the Sub-continent rising, Haqqani issued a statement, saying, 'Pakistan's conduct after Mumbai attacks has been consistent with international expectations. There is no justification for threats against Pakistan'. 'Pakistan is also a victim of terrorism and will continue to act against terrorists'. 'We are a country of rule of law and need evidence to prosecute anyone for the crime of terrorism', he said.
